Change contact list on profile page

This will change the contact list on the profile page. If you look at your own profile a list of 8 contacts will be shown and under the list is a 'see all'-link to your own contacts-page. If you are on another users profile and the user shares a list of contacts with you, you will see the list the same way, with a link to the users contacts-page.

All in all the contacts are now part of the profile information.
